(hey, it's a start)

OpenSRF
IT'S...
 That thing that Evergreen needs
 Based on XMPP
 A load­balancer
 38% cooler than sliced bread

But, let's start at the beginning

We need something that
 Can cross a firewall
 Has low (or no) amortized connection setup
 Has low per­message overhead
 Uses distributed service
 Is going to be around for a while

Decisions, decisions
 spread
 Language­specific (JNI, etc)
 XMPP
 Build our own
 … nothing? (Pile­o­Apache)

High up (thank's Bill)

Low Down

Interfaces
 XMPP (Jabber)
 XML­RPC (Web)
 OpenSRF Gateway (Web – JSON, XML)
 OpenSRF HTTP Translator (AJAX)
